After Re-Install of Palo Excel 3.2 some databases not found

After re-installing Palo Excel 3.2 latest version, I can not access two databases that I had worked with
only a few months ago.
The only accessible databases are Biker and Demo. I have made changes to those and confirmed that
the right folders were adressed (as given during the installation process).

Can somebody help?

Thanks in advance for a quick response as I need to access those databases and the included cubes and dimensions urgently.

thanks for the quick answer.
I have tried this without success.
Also created new database to confirm that the installation does work in the correct folders and it does. I can see all the changes I do in recognized
databases and in the newly created one.
I had my own database folders removed from data folder - after deactivating MOLAP server - copied database back into data folder, restarted the MOLAP server.
